Recording or reproducing apparatus using a stabilizing pad

Abstract

A recording or reproducing apparatus for recording or reproducing information by relatively moving a head and a sheet recording medium is disclosed. The recording or reproducing apparatus includes a stabilizing member disposed around the head and arranged to generate pressure which brings the recording medium into contact with the head in accordance with the rotation of the recording medium. The stabilizing member includes a first projection portion having a projection surface projecting toward the recording medium, a second projection portion disposed outside of the first projection portion via a groove portion formed outside the first projection portion, the second projection portion having a projection surface projecting toward the recording medium, and a cut portion formed in a portion of the second projection portion downstream from the head in a direction of rotation of the recording medium, the cut portion being formed by cutting the second projection portion from its surface which confronts the recording medium, and the depth of the groove portion with respect to the recording medium being reduced from the outer portion of the stabilizing member to the inner portion of the same.

What is claimed is: 
     
       1. A recording or reproducing apparatus for recording or reproducing information by relatively moving a head and a sheet recording medium, said recording or reproducing apparatus comprising: a stabilizing member disposed around said head and arranged to generate pressure to cause said recording medium to contact said head during rotation of said recording medium, wherein said stabilizing member comprises:   an inner portion and an outer portion corresponding to an inner and outer portion of the sheet recording medium,   a first projection portion having a projection surface projecting toward said recording medium,   a groove portion provided adjacent said first projection portion,   a second projection portion spaced from said first projection portion via a groove portion, said second projection portion having a projection surface projecting toward said recording medium, and   a cut portion formed in a portion of said second projection portion downstream from said head in a direction of rotation of said recording medium, said cut portion being formed by cutting said second projection portion from a surface of which confronts said recording medium, and   the depth of said groove portion with respect to said recording medium being reduced from the outer portion of said stabilizing member to the inner portion thereof.   
     
     
       2. A recording or reproducing apparatus according to claim 1, wherein the bottom surface of said groove portion slants from the inner portion of said recording medium toward the outer portion thereof. 
     
     
       3. A recording or reproducing apparatus according to claim 1, wherein said stabilizing member further comprises a circular negative pressure generating member disposed around said head. 
     
     
       4. A recording or reproducing apparatus according to claim 3, wherein said first and second projection portions are concentrically arranged around said head.
